Well here it is 2016 and have run into what everyone else is talking about in this forum. Attempting to replace my wife's HD but can't find the proper driver to remove the 10 screws on the back cover. Some have said it is a 5 point drive others say it a rounded 5 point driver (if that makes any sense) and yet other say a T4 is needed. So my apple has succeeded in befuddling everyone as they intended.
Can someone clear up this mess and steer me at the tools set needed here. Surprised Ifixit doesn't jump in here and answer these questions so ordering the right kit can be a solution.
